NOSE-GUARD FOR EYE GLASSES.

Specification of Letters Fatent.

Patented Feb. 4, 1908.

Application fiiei February 12. 1907. Serial. No. 357.046.

To all whom it may concern:

Be it known that I, DALLAS F. GREEN, a citizen of theUnited States,residing at Fort Wayne, in the county'of Allen, in the State of lndianahave invented certain new and use ful Improvements in Nose-Guards forEyeglasses and I do'hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form part of thisspecification.

My invention relates to' improvements in nose-guards for eyeglasses.

The object of my invention is to provide an eyeglass guard adapted todirectly apply' the holding pressure thereof at the point where thegreatest frictional contact is required in use, and at the same timepreserve the desired elasticity of the guard to secure a ready selfadjustment thereof in conformity to its holding surface and also tosecure such a compactness of arrangement as to materially reduce theusual unsi htliness of the guard without impairing its sasticity.

My resent invention consists 'of a noseguard for eyerglasses formed of asingle piece of spring-metal, preferably having its lower extremityconsiderably extended to increase its holding power, and having itsupper portion provided with an inwardly extended coiled springconnection with the supporting lens clip in compact relation therewith,and adapted to materially aid the self adjusting flexibility of theguard.

The principal novel feature of my invention resides in the means forimparting to the guard its elasticity, and for rigidly securing it uponits mounting.

Similar reference numerals indicate like parts throughout the severalviews of the drawings in which Figure 1 is a rear elevation of a pair ofeyeglasses partly broken away, and showing the relative arrangement ofmy invention in operative position. Fig. 2 is a plan view of the same-Fig. 3 is adetail sideview of my invention showing the manner ofsecuring the same, in position, the lens-clip to which it is securedbeing shown in cross-section on line x-w of Fig. 1 looking to the left.Fig. 4 is a similar View with the section of the lensclip omitted. Fig.5 is a 'side-yiew of the same showing the portions of the guard fromwhich the coiled springs are formed as they' 'appear in the blank. Fig.6 is a vertical central section. of that portion of the lens-clip shownin Fig. 3 and taken at right-angles to such cross-section. Figs. 7 and 8show a slightly modified form. of my invention, in which the blank fromwhich the coiled springs are formed is not integral with the guard andhas the outer ends-thereof integrally united. Fig. 9 is a side view ofanother slightly modified form of my invention in which the coil springsare formed of a single piece of wire, which in the blank is in the formof a narrow horizontally arranged loop whose looped end is soldered tothe guard at or near its inner edge, as shown in Fig. 10.

The lenses 1 of the usual construction, are provided at their inner endswith the, usual or other proper lens-clip 3 by means of the bifurcatedstuds 2 and the stud screws4, and are yieldingly connected in the usualhori- Zontally alined relation by means of the bridge spring 5. ofcommon form whose ends are rigidly connected to the respective clips 3by means of the holding screws 15, Fig. 6, in

the usual manner.

The body 6 of the nose-guard may be of any proper contour anddimensions, and may be formed of any proper material, but is preferablymade of suitable spring metal and in the general outline of a human earwith the lower portion 14 inwardly and forwardly extended to exert abracing action upon the nose in use. The'body 6 may also have anydesired'size and-number of lateral apertures as shown to admit portionsof the nose-surface, and thereby increase'its holding powerin a wellunderstood manner.

The front of the guard-body is provided, somewhat above itslongitudinally central portion, with a pair of springs 7 eitherintegral, as shown in Figs. 3, 4 and 5, or fixed thereto in any propermanner, preferably by riveting as shown In Figs. 7 and 8 or bysoldering, as shown in-Figs. '9 and 10. When these s rings are integralthey are preferably forme from a pair of blanks 9 extending inw'ardlyfrom the inner, edge of the guard in slightly oblique relation withtheirnee ends 8 turned to a vertical position and in ap roximatelyparallel relation, as shown in igs. 4 v

and 5. These free ends 8 are properly separated and may be oppositelynotched upon their adjacent edges to receiving the holding screw 15 inthe cllps 3, andare arranged ad jacentto the inner face of thebridge-spring 5, as shownin Fig. 6. The blanks 9 are each formed intoone or more coils attheir inner end to form the coil springs 7 afterwhich the ends 8 are arranged in their normal relation as before. 7 V

When the blank from which the coil springs are formed is fixed inpositionby riveting it is preferably in the form shown at 12 in Fig. 8,1n which the sides thereof'are connected at the outer end as at 10, andis fixed to the clip-by the screw -]5 which passes through the opening11. The coil springs 7 are formed from the blank 12 bythreading I theinner end thereof through the longitudinal opening therein and coilingit upward in an obvious manner. a

-Where the springs 7 are formed of a single piece of wire, the wire isfirst formed in a.

tween the nose-guard and the supporting lens-clip enables me to secure avery compact arrangement which'obviates the usual un-' si htlines's'thereof, and materially. aids, the 'se f adjusting flexibility of thesaid guards,

and consequently increases the comfort and convenience with which theyareiworn.

Having thus described my invention and, the manner of operating thesame, what I desire to secure by Letters Patent is:

1. A nose-guard foreye-glasses consisting of an apertured guard-platearranged entirely atthe rearof its support, and provided upon itsforward edge'with anfin'tegral coiled heli-" cal spring arranged bothaboveand below its support, adapted to multiply the self-adjust.-

ing flexibility of the guard, in combination with a spring nose bridge;v 2. In a nose -guard for eyeeglasses formed) entirely of spring metal,an oblique spring metal apert ired guard-plate arranged at the 7 rearofits support, and provided substantially; j 15 3., coiled helicalspring-connection to the sup midway of its ends with-a divided lateralporting lensclip to increase the self adjusting properties of the guardin combination with a spring bridge. t 3. The combination -1neye-glasses of a arranged entirely at the rear of the said bow, andprovided u on its front edge with coiled helical springs means of whichit is fixed its self-adjusting flexito its sup ort and bility isincreased. p

' 4. An eyeglass nose-guard fbrmed ofan a 1- ertured spring metal platearranged at t e rear of its support, and united to the support- 1 inglens-clip at the rear ed e thereof by meansof a divided coiled helicaspring connection in compact arrangement, whereby the self-ad justingflexibility of the guard is appreciably multiplied in combination with aspringbow. 1
